Plasterers and Stucco Masons

So far, robots and AI have only started to show up in plastering work. For example, engineers have built a robot that can spray and smooth mortar on walls ^[1], and another prototype can pick up and sort construction debris ^[1]. A construction industry article even says robots and AI are “poised to redefine how we build” scaffolds ^[2], though this is mostly talk about the future.

In everyday work, however, plasterers still do almost everything by hand. They set up scaffolds, mix and apply plaster with trowels or brushes, and clean job sites manually ^[3]. We found no widely used AI tools for tasks like estimating materials or creating decorative plaster textures.

In short, today’s machines only help a little with heavy or repetitive parts (like spraying even coats); the creative and finishing work is still done by skilled people.

Adoption of AI and robots in plastering is likely to be slow and cautious. One reason is cost: building or buying a plastering robot is expensive, so firms will only invest if they really save money. For instance, a report notes that robots can work without breaks and could cut project time and cost ^[2].

But someone must pay for that robot up front, and on a busy, uneven jobsite machines can struggle. Another factor is labor supply: if plasterers become hard to find or very expensive, companies might look to machines for help. If not, they’ll stick with trained workers.

Social and legal factors matter too. Most customers and codes expect a human to check fine details and quality, especially for craft work. Industry experts say we are still at the “dawn of a new era” of construction robotics ^[2], meaning change is just beginning.

Since plastering needs manual dexterity and artistry ^[3], full automation isn’t coming soon. Plasterers can take comfort that their creativity and hands-on skills remain valuable, even as new tools (like planning software or safety aids) arrive ^{[2] [3]}.
